My company's flying manuals mention this technique, but discount it in a risk-management formula against the increased risk of tailstrike.
Interestingly, the contaminated braking co-efficients acceptable for the 320 have just been clarified... down. Essentially we can now land on "slippery" runways, but not take-off.
Don't know if I'm brave enough for that, might be time for a little Commander's discretion to be applied there.
